Luminus SST-40, a N4 BA bin tested

Thanks for the testing :slight_smile:

If anyone has seen the N5 or P2 bin listed, I’m keen to grab a few.

Thanks for the test. I like what i see!!! So the Q8 with VTC6, mod ledboard and SST-40 P2 Bin will draw something about ~30A. Maybe even more. :smiling_imp:
The low Vf is really nice! The low CRI is not so. But i am curious how much output the Q8 would get with the P2 Bin SST-40? 8000+lumen?

Aside from the low CRI how does the light look? Is the beam ringy with color artifacts like the newer crew emitters, or is it fairly consistent?

I’m sorry to say I don’t know, I had 2 emitters, one died in the test, the second was dedomed. The dedomed tint is towards a bit yellow, but a good tint, a quite uniform hotspot with a very thin blue-ish edge around it. Nothing of the problems of the new Crees.
One thing I seem to notice is that the led has a large tint shift going from low to high current, the good tint only happens at highest modes when the BLF driver mainly uses the FET.

Wow, impressive graph!
7.5 Amperes seems to be sweet for this thing, at only 3.6 Volts. !
That’s 27 Watts, but ‘just’ a bit under 2300 Lumen.
2000 lumen at around 20.5 Watts though.

Happy to hear the tint looks decent. I have one coming with my next order, got it just to play with, but I’m quickly thinking of uses.

Thanks for the most excellent analysis. :+1:

Sounds like this may be good to upgrade my Supfire m6 with

Thanks for the detailed rundown of this emitter. I got a itch to have a light with each worthy emitter, and I think this would be a good one.

I’m actually a fairly big fan of the SST-50 for it’s efficiency. At higher amps it’s heat can be a problem but for running at low amps it does a wonderful job. One of the lights I use most often is a cheap sharp eagle zoomie with a de-domed SST-50 in it. At low amps it’s still fairly bright and a good 26650 seems to go forever without needed a re-charge. I don’t have the equipment to test it but I always suspected that it must be VERY efficient at low amps. Too bad they are so pricey.

But good news on these new ones. I’ll have to get my hands on a few and see what I can do with them.

Either you’re very wrong or fonarevka’s calculator is:

(click ‘calculate’ button under that url)
SST-50 is not efficient, not at all.

Impressions are never ‘wrong’ :slight_smile:

I just received five SST-40 from this seller on Aliexpress, they turned out to be the real deal. There is of course no specific information about tint/bin but with my unscientific testing they seem on par with the one I bought from KD.

There is also a bit of green in the lower modes just like the one from KD. The MCPCB’s is not very good but that didn’t come as a surprise. The price has gone up a bit I payed $1.69 a piece.

Nice, I’m always a little leery of buying emitters for aliexpress, but they have done pretty well with flashlights and other things. One thing about them, if you order from them and they don’t come through, you get your money back, no problem.

Nice, the AE seller is really cheap.
And some nice dedoming you did there! :slight_smile:

After luminarium iaculator revealed his metode in this thread and I happened to be in Italy so I could buy the “magic” fluid they turn out great every time :smiley:

Put my SST-40 from KD in a Convoy M1 with a MTN-17DD fet+1 driver and I Really like it. The tint almost has a purplish color to it at higher amps, but not in a bad way, very pleasing to the eye, especially for low CRI.

Hey can you show us the sst40 dedome beamshot?? I don’t mind about the camera quality… you can use postimg.org for loading. Thanks.

I would, but mine is not de-domed, just installed as it came from the factory. Beam looks almost identical to a typical XM-L2 in the M1.

Tempting LED in all, but would be nice to have higher brightness bins available somewhere (for EU).
Still, 2000 Lumen at 20 Watts at 3.6 Volts and 5.6 Amperes is very nice.

Nice find. Thanks for sharing.
